SPECIFICATION forming part of Letters Patent No. 431,965, dated July 8, 1890.

Application filed August 13, 1886. Serial No.210,84l (No model.)

To all whom, it may concern:

Be it known that we, OSCEOLA R. COQK and LEONARD l IINDS, citizens of the United States,

residing at Providence, in

the county of Provi dence and State of Rhode Island, have invented a new and useful Improvement in llair- Clipping Machines, of which the following is a specification.

Our improvement relates to the form of the lower er stationary cutting-plate, whereby the machine may be .fulcrumed on the surface to be clipped and a rocking mot-ion imparted to the machine for the purpose of gradually varyingthe length of the hair,

tion of shingling the l in the operaiair7 and our invention also relates to the details of construction, as hereinafter described, and set forth in the claims.

The drawings hereunto annexed represent a hair-clipping machine tures of our invention.

embodying the fea- Figure l is a top view with the pressureplate removed. Fig. on line X X, Fig. l. Fig. portion of the machine, been removed. Fig. e i tional view on line lV IV is a sectional view 3 is a side view of a the handle having s a transverse sec- Fig. Fig. 5 is a detached and top view of the pressure-plate,

and Fig. (3 is a diagram of a rocking motion.

A denotes the lower or showing the effect stationary cuttingplate, and A the upper or movable cuttingplate, each having the serrated edges provided w1th teeth ja and spaces fi', as is usual in machines of this class.

The plateA is attached rigidly to the handle I3. The opposin g handle 13 is pivoted a t Rand is extended serving both as guides t rocating motion of the pl stop to limit its motion o control the recipate A and also as a in either direction.

The plate A is held against the plate A, so

as to insure the proper cutting' action of the' edges of the teeth fi, by means of the curved pressure-plate C, whose forward edge rests in a groove d m the upper surface of the movable cutting-plate A.

At the opposite or .rear side of the pressure-plate a hub e is formed, having a hole c', which lits loosely the pivotal pin I. rlhc nut D enables the cuttinplates to be brought together with any desired pressure. Between the handles I3 I we place the bent blade-spring E, whose ten sion maintains thc handles apart when in their normal position, with the movable cutting-plate A against the stud Z1.

IVe make the machine as narrow as possible at the cross-section passing through the pivotal pin P, gradually increasing it in wid th to afford a sufficiently long cuttingedge and making the lower plate A fanshapet and thereby permittingthe free use of the machine in situati-ens otherwise inac-y cessible. This result we accomplish hy extending the fixed handle 4l' forward of the pivotal pin P and expanding it laterally to afford a surface, upon which the lower plate A is securely fasten ed. From the pivotal pin P rearward the handles Il B are slightly curved upward for a short distance, and from the pivotal pin forward the entire under surface, formed in part by the forward extension of the fixed handle and in part by the stationary cutting-plate A, is curved, forming a circular are, with its convexity downward and tangential to the oppositely-curvcd section of the handles B B. This conformation, which is a distinguishing feature of our improved clipping-machine, enables the convex surface of the lower plate to be placed against the surface to be clipped, and a rocking motion to be imparted to the machine as it is simulta neously moved forward and the cutting action of the toothed edges at' the same time continued. The convert surface resting upon the surface to be clipped serves as a fulcrmn,upon which the cutting-edges are raised by depressing the handles, vice versa, and thereby varying the length of the hair while the operation of cutting is carried on. In Fig. 6 the result of this rocking motion in varying the length of the hair is illustrated by a diagram, in which the line l4 2 indicates the surface over which the machine denoted by the curved line I3 is to pass. At the endl, the hai idles being raised, the cutting-edges are brought close to the line l 2, cutting the hair short. As the machine is advanced and its IOO | l 2 l l cutting laction continued, the handles; are gradually depressed uniformly with the forward motion of the machine to the position at the opposite end of the line 1 2,euttingthe hair on the line 1 4.

W'e do :not confine ourselves to any particular shape or amount of curvature,y nor is it necessary that the curvature should extend entirely to the forward or cutting edge,as the portion of 'the lower cutting-plate occupied bythe cutting-teeth 'i may remain a plane-surface, if desired, for convenience of constructerwit being easier to cut and gri nd the edges of the teeth in a plane than in a curved surface.

W e are aware that hair-clipping machines have been heretofore made provided with a curved bottom plate upon whichthe machine rested and upon which it was rocked while employed in the operation of hair-cutting. Such we do not claim, broadly, as such a curved bottom plate was shown in Patent No. 330,535, granted to Whittier and Denlon, November 17, One of the distinguishing` features of our present invention, however, consists in the relation of the curved rocking' surface to the plane of the cutting-teeth, said plane being made tangential to the curved.

surface upon which the machine rests and upon which it is rocked, therebyallowing;the under surface of the cutting-teeth to rest upon the surface to be clipped and their plane to coincide with the surface to be clippedn lf the machine! is gradually moved forward and at the same time uniformly rocked upon its lower curved surface, the compound motion ef the ri-,whine will cause the plane of the cutting-teeth to describe a straight line, as illustrated in Fig'. (3 of the drawings.l,` This action of they machineis very essentia1 perform ing the operation of shingling, fro, i. the fact that at cach of the vibratory movements of the movable covering-plate the hair is clipped nearly or quite the entire length ot' the cutting-teeth, and in case the plane of the teeth does not describe a straight line as the result of :the compound motion of the machine, as .above described, the cutting-teeth at each Vibration of the cutting-plate will form a ridge or step XVe are aware that a curved plat-e has been secured to the under surface of the eombplate, forming` abearing upon which the head of the machine rocks as the machine operated. Such a curved plate was shown in lietters Patent of the United States, No. lidi. Such we do not claim; but

That we claim as of our invention, and desire to secure by Letters latcnt, `isl. ln combination, the movable en tti ngwplat e and pivoted aetuati11g-handle, the stationary cutting-plate and lxed handle attached there to, said stationary plate and lfixed handle bcinter curved between the cutting-edge and the axis of the pivoted handle, and a series ol' cutting-teethformed upon the correspoiuline' edges of the stationary and movable jjilates, and said teeth lyingr in a plane which is tam gential to the curved section of said stationary platc, substantially as described.

2. In combination, the stationary cuttingplate and lixed handle attached theret the movable cutting-plate and pivotcd actuatin handle, said stationary plate and lixed handle being curved substantially in the are ot' a circle between the cutting-edges and. the axis of the pvoted handle, said curved section having its convex side dowi'iward and forming;` a rocking' surface upon which the mw chine rests when in operation, substantially as described.

In combination, the stationary cutting-- plate and fixed handle attached thereto, the movable cutting-plate and pivoted. actua ti n handle, said stationary plate and txed hand lo being` curved substantially in the are et a cr cle between the cutting-edges and 'the airis ol the pivoted handle with its convex side down ward, and a pressure-plate curved substialr tially in the are ol a circle with its convex side upward, said pressure-plate beine' held onthe pivotal pin of the aetuating-lntndle with its edge resting on said movable plate, substantially as described.
